I have a Brand New In Box Brugger & Thomet Integrally Suppressed APC9SD - pistol and suppressor kit. The APC9SD - like the H&K MP5SD - uses a ported barrel in concert with the sound suppressor to reduce the velocity of all 115 grain and 124 grain ammo to subsonic speeds. This means you can shoot the cheap stuff and still get a much quieter report from the weapon.
I have one kit currently in my inventory on Form 3 available for immediate Efile. Grab one of these now if you want one soon.
